Objective To explore the relationship between m6A methylated genes and prognosis of ovarian cancer, so as to provide scientific basis for targeted therapy and prognosis assessment of ovarian cancer. Methods The mRNA expression data of ovarian cancer tissues and normal tissues were downloaded from TCGA and GTEx databases for difference analysis between two groups. The genes related to ovarian cancer survival were screened by LASSO regression, and the risk score prediction model was further constructed by step Cox regression analysis. The patients were divided into high-risk group and low-risk group according to the median risk score, and the ROC was used for analysis. Correlation analysis was performed to construct an expression regulatory network with m6A genes, and GO function enrichment and KEGG pathway analysis were performed to preliminarily explore the potential biological mechanism. Results 20 m6A methylation genes were found in differential expression between cancer tissue and normal tissue, three genes (HNRNPA2B1, ZC3H13, WTAP) were used to construct the model through step Cox regression analysis. Patients' survivals of high-risk group were shortened than that of the low-risk group obviously (P=0.001 9), the risk of death significantly was increased (HR=2.643, P<0.01). After risk score model combined with patient age, clinical classification and stage, the AUC of 1, 3, 5 years was 0.74, 0.64 and 0.64. Bioinformatics analysis indicated that those m6A genes were involved in RNA splicing, localization, transport, metabolic regulation, proteolysis, cell cycle, ribosome synthesis and other biological processes. Conclusion The prognostic risk assessment model of m6A methylated genes for ovarian cancer was successfully constructed and the model had certain predictive efficacy.

Objective To investigate the effect of reversine (REV) on bile duct ligation (BDL) -induced hepatic damage, fibrosis, epithelial-mesenchymal transformation, and ductular reaction in rats. Methods Male Lewis rats were randomly divided into three groups with 5 rats in each group. Bile duct ligation was performed in the BDL group for two weeks. BDL+ REV group was treated with bile duct ligation and intraperitoneal injection of reversine. The control group was Sham operation (Sham). Blood and liver tissue were obtained after 2 weeks. Blood indexes were determined for total albumin, total bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hepatic histopathology was detected by H&E staining. Azan staining was used to detect tissue collagen deposition. Immunohistochemistry was used to detect the expression of α-SMA, desmin, vimentin, cytokeratin, β-catenin and epithelial cell adhesion molecule (EpCAM) protein. Results Bile duct ligation resulted in the decrease of total albumin synthesis in liver, and the increase of total bilirubin, glutamic-oxalacetic transaminase, alkaline phosphatase and γ-glutamyltranspeptidase. The levels of total bilirubin, aspartate transaminase, alkaline phosphatase and γ-glutamyltranspeptidase returned to the normal level with reversine treatment. Reversine could alleviate cholestasis-induced liver fibrosis by downregulating BDL-induced deposition of collagen and α-SMA protein. Reversine inhibited cholestasis-induced epithelial-mesenchymal transformation by significantly reducing BDL-induced desmin and vimentin expression. Reversine could inhibit cholestasis-induced ductular reaction by significantly reducing the expression of CK7 and CK19 positive biliary cells. Inhibition of cholestasis induced ductular reaction by reversine was associated with regulation of β-catenin and EpCAM expression. Conclusion Reversine can alleviate liver damage caused by cholestasis in rats and have a protective effect. Reversine may be a potential treatment that need further investigation.

By applying the questionnaire and Kupperman score table, the survey was conducted on the dates of birth, menstruations, times of menarche and menopause, records on pregnancy and childbirth, previously diagnosed diseases, heights, weights, classifications of work, family incomes, and personalities, etc. Results The average age of the 1 013 women was 47.70±4.95. Among them, 267 were with menopause (happening in 49.49±3.26 years old), 458 had regular menstruation, while 288 were with menstrual disorder. In the Kupperman scale, the scores of 392 cases (38.7%) were above 15, which can be diagnosed with menopause symptoms. Among them, the majority (222 cases, 56.63%) were with slight symptoms (15-20 scores), followed by 162 cases (41.33%) with moderate symptoms (21-35 scores), and 8 cases (2.04%) with severe symptoms (above 35 scores) respectively. Logistic regression analysis demonstrated that compared with women having satisfactory family relationship, participants suffering from chronic diseases, menstrual disorder, and poor family relationships, had higher risks of perimenopause. However, it had no relations with the marital status, personalities, working hours, social adaptabilities, and negative life events. Conclusion Guangzhou urban women with menopause symptoms are mainly slight and moderate. Participants with chronic diseases, menstrual disorders and poor family relationships are at a higher risk of having menopause symptoms. Therefore, it is recommended to popularize the knowledge of menopause in the society and attach importance to the maintenance of satisfactory family relationship. When perimenopausal women have relevant symptoms, they should seek medical help in time thus they can smoothly pass the peri-menopausal stage.

The bacteriostatic effect of decoction was better than decoction-free granules. The bacteriostatic effect of AB was weaker than Staphylococcus aureus, but there was no significant difference between them.
目的 粪菌移植(fecal microbiota transplantation,FMT)是治疗疾病的新途径,本文总结我院408例(1 085例次)FMT的临床疗效和安全性。FMT治疗艰难梭菌感染有效率达80%,抗生素相关性腹泻68%,炎症性肠病52%,功能性肠病65%,代谢性疾病50%,其他疾病57%,安全性良好,未见严重不良事件发生,结果和多数文献相符。还需更多随机对照试验才能明确FMT的临床价值。
目的 分析脑出血(intracerebral hemorrhage,ICH)在SWI和CT中的影像学表现,比较SWI和CT两种检查方式在ICH及脑微小血管出血(cerebral microbleeds,CMBs)中的优势。方法 采用回顾性分析2018年1月—2019年12月在广州市第一人民医院收治的76例疑诊ICH患者行SWI及CT检查,对确诊为ICH及CMBs的病例数据进行统计。结果 SWI与CT在ICH诊断结果的比较,差异无统计学意义(P>0.05);在CMBs诊断结果的比较中,SWI诊断准确率高于CT(P<0.05);另外在SWI与CT的联合检查中,诊断准确率高于SWI与CT独立检查。结论 脑出血患者的SWI和CT的影像表现均能将出血灶显示清楚,除此之外,SWI还能发现CT未能发现的有关血管的微小病灶。SWI作为一种新型技术,在ICH及CMBs方面起着至关重要的作用,与CT相辅相成。两者在医疗诊断中扮演着不可或缺的角色,为医疗的精准实施保驾护航。
目的 探讨无偿献血者ABO血型正反定型初筛结果不一致的原因分析。方法 选取2019年6月1日—2020年11月30日本血站的无偿献血者样本,采用Metis150全自动血型分析仪进行ABO正反定型初筛。初筛结果正反定型不一致先进行试管法复核,结果仍不一致时送血型参比实验室做进一步确认,并对造成ABO血型正反定型不一致的原因进行分析。结果 44 808例无偿献血者样本中初筛结果ABO血型正反定型不一致134例,发生率为0.30%。导致ABO正反定型不一致原因为:因方法学不同可经盐水介质试管法复检确认65例(48.51%);吸取红细胞或血浆异常加样量不准确25例(18.66%);仪器判读错误4例(2.98%);血型参比实验室通过延长反应时间或改变反应温度确定因抗体缺失或减少22例(16.42%)、冷凝集素2例(1.49%);增加抗A1、抗AB、抗H血清和吸收放散试验确定亚型6例(4.48%)、抗原减少2例(1.49%);洗涤自身红细胞吸收放散后定型、吸收后血清反定型确定不规则抗体8例(5.97%)。40例血型参比实验ABO血型血清学检测结果为:O型21例(52.50%)、A型8例(20%)、B型7例(17.5%)、AB型4例(10.00%)。结论 ABO血型正反定型不一致的原因很复杂。严格规范操作,减少不规则抗体对结果的影响,防止弱亚型的漏检等有效措施确保临床输血的安全。
